RegisterBluetoothComPort function question in bluetooth test

Hi:

we have a MIPSII BSP and board with UART 0,1,2,3
BSP uart driver define(nxc26uart.reg) and suport physical com port 1,2,3,4

i take reference from :
http://vinoth-vinothblog.blogspot.com/2008/10/enabling-bluetooth-serial-port-profile.html
and AP sample
c:\Wince600\PUBLIC\COMMON\SDK\SAMPLES\BLUETOOTH\COMTEST\comtest.cxx

then write an AP to simulate blooth manager.

at the call h=RegisterBluetoothComPort(L"COM",index,&pp));or
h=RegisterDevice(L"COM",index,L"btd.dll",(DWORD)&pp);

h return NULL ,index=1,2,3,4
h return handle, if index=0 or index>4

but uart driver support physical com1,2,3,4 and com4 connect to bluetooth
module.

so i confused how i can use com4 in the AP
h=RegisterDevice(L"COM",index,L"btd.dll",(DWORD)&pp); ?
why index in 1..4 return NULL?

hope to get your comment

Thanks
Regards.

one thing is the (physical) UART which is connected to the BT controller
(COM4: in your case), another thing is the (virtual) serial port that you
create with RegisterBluetoothComPort + RegisterDevice to communicate with a
BT device which exposes the SPP: the virtual port musrt have an index which
is not already in use: since your HW has already COM1:...COM4: you have to
use an index which is >4 or 0

Thanks Luca Calligaris input.
by the way, i cannot understand the map relation of COM4 and com"index"?
should i call a function to make the mapping of COM4 to this virtual
com"index"?

Hi ,

If you are using com 1-4 for physical port, you cannot use it for virtual
comm port.

Only free ports from 0-9 can be used for the same.

Thanks Misbah input.
i can understand this.
i meet another relation question so i describe into nother new quetion with
new subject
"physical UART interface with bluetooth driver stack question"

anyway thanks again.
